Gagging during a blowjob

Moriah
My man thinks it's REALLY sexy when I gag while giving him a blowjob but I feel REALLY awkward when it happens and I feel like an idiot. How is it sexy? Should I keep doing it? Sometimes I do things I don't want to do because he likes it and at that moment I'm pleasuring him and it's not about me. the gagging is something that makes me very uncomfortable but the way he reacts when I do it is pretty sexy and sometimes a turn on.
